Ah.  I think "R 49" means "reserved by document 49".  See footnote
(d), third bullet point.  It appears to be applied only to reserved
code elements.

In might the Feanorians / that swore the unforgotten oath
brought war into Arvernien / with burning and with broken troth.
and Elwing from her fastness dim / then cast her in the waters wide,
but like a mew was swiftly borne, / uplifted o'er the roaring tide.
